Column assignment is as follow: * DYNAMO_2011_ceilo_15s_a.txt. 1 Year day 2 N, where N=number of cloud layers (0-3) or a code (4-5) for marginal clouds (4 is full obscuration determined but no cloud base detected; 5 is some obscuration detected but determined to be transparent) 3 Height of the first layer in meters (NaN unless N>0) 4 Height of the second layer in meters (NaN unless N>1) 5 Height of the third layer in meters (NaN unless N>2) * * DYNAMO_2011_ceilo_10min_a.txt and * DYNAMO_2011_ceilo_h_a.txt (1-hour) 1 Year day 2 number of data points in selected window section (10-min or hour) 3 number of clear samples 4 number of times at least one layer is present 5 number of times second or third layers are present 6 Obscuration cases (code 4 or 5) 7 number of partially obscured cases (code 5 only) 8 Clear fraction 9 cloud Fraction (cloud only) 10 cloud Fraction (cloud + oscure cases) 11 cloudbase heights (m) 12 + standard deviation of cloudbase height (16%) 13 - standard deviation of cloudbase height (84%) * cloudbase_yyyy_mm_dd_doy.txt daily cloud base information 1 N, where N=number of cloud layers (0-3) or a code (4-5) for marginal clouds 2 Height of the first layer in meters (NaN unless N>0) 3 Height of the second layer in meters (NaN unless N>1) 4 Height of the third layer in meters (NaN unless N>2) 5 hour (utc) 6 min 7 sec 8 Year day * backscatter_yyyy_mm_dd_doy.mat are raw variables saved into a binary MAT-file form. To retrieve the data, use the load function of Matlab. 1 UTC time in decimal hours 2 Range of each gate in m 3 Sensitivity normalized backscatter coefficient in the unit srad-1.km-1
